Proportional directional valves in ruggedexecution with integral electronics andspool position transducer.These valves are derived from therelevant standard servoproportionalversions, specially modified in order towithstand high vibration levels andmechanical shocks typical of heavy dutyapplications like wood industry.Technical characteristics
• DHZO and DKZOR, size 06 and 10 aredirect operated proportional valves,with LVDT position transducer.
• DLHZO and DLKZOR, size 06 and 10are high dynamic, direct operatedproportional valves, with zerooverlapped spool coupled with anhardened sleeve for the bestmechanical accuracy. The LVDTposit ion transducer ensures highlinearity and repeatability.
• DPZO are size 10, 16 and 25 pilotoperated proportional valves with singleor double LVDT position transducer.
• Ruggedized design tested undersevere conditions, see section 12
-Vibration test up to 55 Hz, amplitude1mm and acceleration 6 g
-Shock test at 50 g

16.5 Dynamic responseThe response times in section � and the response in bode diagrams have to be considered as average values.For the valves with digital electronics the dynamics performances can be optimized by setting the internal software parameters.
16.6 Oil ports configurationThe standard configuration is internal pilot through port P and external drain through port Y. If the working pressure is over 100 bar, select option /G toreduce the piloting pressure or select the external pilot (option /E). The minimum piloting pressure is 30 bar. In case the system pressure could drops atvalues lower than 30 bar, select the external pilot (option /E). The internal drain, option /D, can be selected only if the backpressure on port T is < 1 bar.
